The abrasion protection tape for machine tools is a high-end guide rail soft belt product for all kinds of precision machine tools, CNC equipment and machining centers. The composite machine tool abrasion protection tape is rich in solid lubricant particles and has excellent friction and wear characteristics. What are the basic requirements of the abrasion protection tape should meet?
1. Guiding accuracy
Guiding accuracy refers to the linearity of the linear motion guide when the abrasion protection tape of the machine tool moves along the supporting guide rail, the roundness of the circular motion guide rail, and the accuracy of the mutual position between the guide rail and other moving parts. The main factors affecting the guide accuracy are: The geometric accuracy of the abrasion protection tape, the contact accuracy of the abrasion protection tape and the structure of the guide rail, the structural rigidity and thermal deformation of the abrasion protection tape and the basic parts of the machine tool, the stiffness of the oil film between the dynamic pressure guide soft and the static pressure guide rail, and the friction protection of the machine tool The assembly quality of the belt and so on.
The rigidity of the machine tool abrasion protection tape is an important indicator of the working quality of the machine tool. It represents the ability of the abrasion protection tape to resist deformation under dynamic and static loads. The uneven distribution of specific pressure on the rail surface increases the wear of the rail, so the rail must have sufficient rigidity.
3. Abrasion resistance
The uneven wear of the abrasion protection tape of the machine tool destroys the guiding accuracy of the abrasion protection tape of the machine tool and thus affects the machining accuracy of the machine tool. The friction properties of the guide rail surface, the force of the abrasion protection tape and the relative movement accuracy of the two guide rails are related. The friction coefficient of the abrasion protection tape is less than 0.04, which is only 1/3 of the cast iron guide rail, which can reduce the driving energy consumption. The self-lubricating performance of the machine tool abrasion protection tape is good, and the guide rail can be avoided even if the lubrication system fails.
4. Low speed smoothness
When the abrasion protection tape is moving at low speed or in a small amount, it should be ensured that the guide rail moves smoothly without creeping. The creeping phenomenon of the machine tool will affect the roughness and machining accuracy of the processed parts, especially for high-precision machine tools. Enough attention.
5. Structural technology
When possible, the design should try to make the machine tool abrasion protection tape structure simple, easy to manufacture, adjust and maintain. The amount of scraping should be reduced as much as possible. For the shackle rails, it should be easy to replace, and strive to be good in manufacturability and economy.
The above are the basic requirements of the abrasion protection tape should meet. The machine tool abrasion protection tape plays a guiding and supporting role, that is, ensuring that the moving parts are accurate under the action of external forces (the weight of the moving parts, the weight of the workpiece, the cutting force and the traction, etc.) The movement of the ground in a certain direction.
